More RAM would help tremendously. There is a run on DDR2 out of Taiwan right now, so I encourage you to pick some up when you have a chance. Price is going up. Otherwise… A mouse, a monitor or two. You should be all set. Running Win 7 at the moment on a dual core with 4gbs and it’s a rocket ship, but I had it running on a 2gb Celeron last week and that was faster than XP believe it or not.

@patg7590 Oh sorry, I didn’t understand the question. Well, show people the new taskbar and its features, show them the ribbon in Paint and WordPad, and I think that Windows 7 supports multi-touch so I would get a big multi-touch monitor and demonstrate its capabilities with Windows 7.
